We fabricate a bottle/quasi-cylindrical microresonator by using a fusion splicer. This method does not require a real-time control of the translation stages and can easily fabricate a resonator with expected size and shape. Selective excitation of whispering gallery modes (WGMs) in the resonator is realized with a fiber taper coupled at various positions of the resonator along the bottle axis. Most...
We package a high-quality (Q) factor optical whispering gallery mode (WGM) microsphere resonator side coupled to two tapered fibers without changing the initial coupling conditions, achieving a final Q as high as 2.7×10 6 . The mechanical stability of the coupling system is improved by placing the tapers in contact with the microsphere. The packaged device can be easily sealed in a targeted...
